CREAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 658,455, dated September 25, 1900,

Barill No. 733.387. N0 modem To n-lll whom it may concern.-

Be it known that I, FREDRICK W. Mose- LEY, a. citizen of the United States, residing at Clinton, in the county of Clinton, State of Iowa, have invented certain new and useful Improvements in Cream-Separators, of which the following is a specification, reference being had therein to the accompanying drawlugs.

This in vention relates to cream-separators, and more particularly to a combined creamseparator, milk-cooler, and refrigerating-can for the storage and transportation of milk or cream.

One object of the invention is to provide a can by which several independent methods of cream separation may be eflected and a cooling and transportation can provided.

The can is particularlyadapted for the following methods of cream separation:

First. The Swedish is a system by which the cream can be separated from the milk in from two to three hours by the rapid red uction of temperature, which condenses the watery portion of the milk, thus giving the oily (butter-fat.) portion a denser medium to float in. Hence the cream-globules, being lighter, will rise easily and quickly to the surface. This system is usually practiced by introducing the milk into the can at or near its normal temperature when drawn from the cow and then reducing this temperature toabout 45" by the use of ice or cold water.

Second. The diluting system, in which the cream may be separated from the milk in from sixty to ninety minutes by the addition to the milk of an equal amount of water. The milk in its normal condition contains about thirteen percent. of solid matter, which includes butter-fat, 3.6 per cent; casein, 3.3 per cent.; albumen, .7 per cent; milk-sugar, 4.7 per cent., and ash, .7 per cent. Casein, sugar, and albumen give to the milk a glutinous condition, which retards the cream from readily and quickly rising. This condition is known as viscosity and may be reduced by a proper dilution of the milk with \Vill-L'l, so that the cream will be separated therefrom and rise to the top.

Third. A combined system which includes both th reduction in the tmnpcratureof the milk and the introduction of water to reduce its viscosity. In this system from four to live hours are required, according in tho inmperatnre of the water, and inasmuch as l-ilu cream is separated within a practicality short. time and the skim-milk is but slightly diluted is found very desirable. The amount of dilution with water varies from ten to twenty per cent, dependent upon thi- (legrooof cold to which the milk is snbj ctctl and the character of the milk and truipcrnturo when set.

The invention has for a further object; to provide a construction for cooling milk or cream as a preparation for storage or transportation and to produce a can in which such milk or cream may be maintained at. a low degree of temperature and easily and economically stored or transferred from point to point.

Another important object. of the invention is to provide a sediment device for catching and holding the sediment which collects at. the bottom of a can of milk and preventing: the withdrawal of the some from the bottom of the can when the milk or cream is drawn for use or for the final separation of the cream from the milk.

Other objects and ad vantages of the invention will hereinafter appear in the iollmringi description, and the novel fen-lures thereof are particularly pointed out in the appcrulml claims.

Like letters of rel'crom-iiuil'h'nlv lilti- .'ll'l.\ throughout the several liguri-s ol' the lr.-| lugs.

The let l or A (luh'lgtlttlva tliocau-lm b'. may he of cylimlrir-al or other desired form and is provided with it hen-e A'aml u-l its up per end with a lnmtxt A", morning: inton (wk portion A. This ln'camt muy be rcmovnblv connected to the body A by means of ajoint A, which time permits a. read) cleansing of the can when necessary, and the upper cod of the neck is provided with an ordinary construction of cover A Above the base A" of the can is a pitched or conical bottom 8, inclining from its periphery toward a central point. This is provided from its lowcstcentral point with a rmiiatln' channel B, which at its outer end is lower than the lowest pointof the l-mllulit B and expan is in diameter to ward the periphery of the bottom, time providing It chamber into which may drain any sediment. deposited at the lower portionof the can. This sediment channel or chamber is preferably formed of a separate piece of material from the bottom and joined thereto at'the overlapping edges B'-. By this construction the sediment-channel may be inclined to a suliicientdegrec to drain from the lowermoat point of the hottomB; but if found desirable the bottom could be inclined at an angle toward the front of the can and the channel formed integral therewith by a suit abledeprcssion of the material.- At theoutcr end of this channel an opening 0 is termed in the face of the body A and provided with a threaded boss or not C','secnrod thereto, into which an y suitable form of draw-0E cock or faucet C may be introduced. The structure thus far described would permit any sediment in the chamber B'' to be drained off through the faucet- C; but to prevent this sediment from passing through the faucet when milk or cream is to be drawn therethrongh a sediment-dam D is provided, having a neck I), adapted to closely fit within the end of a shank of the faucet and to be spaced at a distance from the opposite walls of the channel B. This dam is provided with a handle 1) by which it may be readily removed or replaced in position, as desired, and in its general shape conforms to that of the channel in which it lies, although it is of less diameter than said channel.

In the operation of the invention it will bcseen that the milk or cream in order to pass from the can must enter the sedimentdam D, and as this dam is separated at all of its points from the bottom the sediment or other material lying upon this bottom will be carried into the space between the edges of the dam and those of the sedimentrchamher, and thus deposited in said chamber, while the body of milk above the bottom will pass into the dam andthrough the neck thereof to the faucet when deeircd. The on rrcnt of the milk caused by the opening of the faucet carries the sediment toward the chamber, and after the milk and cream are withdrawn from the can the dam can readily be removed and the sediment remaining in the chamber Wlllllll'ittl'll through lluilllll l'nul7 1,ill-l can also any water which may in: uscd for the purpose of olcnneing tin-mu. The proper time for withdrawing the rrwuu illul sediment mm I'hil|lll hr llrlurmiucd by means of the gage A al Lllu up n-r portion 'and gene A at the lower portion of the can.

By the former the amount of crcnm collected :at the topot the milk may be readily ascertained, and the lower gage will indicate when the body of milk has been withdrawn from thocream, so that a different receptacle may beplaced beneath the faucet lo rcceire the cream from the can.

In carrying out the several prucenses hereinbeforc mentioned.- itia essential tocool the milk, and this has been frequently done by sermon-ding the some by a body of cold water or ice, or bot-h.- In connection with the present inven ion, however, a removable coolingehamber E has been provided, which is surrounded by the material to be cooled, and

thus lenders effective all of the cooling ma-- torial used. The coolingchamber is prorid-ed with-a cover E and lifting-handle E, by which it may be removed from the ran through the neck A, and at its bottom with supporting-legs E to maintain the same in a proper position above the conical bottom B. Attention may also be called to the flange E, provided at the base of the neck, by which the milk poured into the can is directed in a -thin stream into contact with the cold surface of the chamber E and passingdown the same is quickly cooled upon ire introduction into the can.

For the purpose of diluting the milk to any degree desirable consistent with the syntem of separation employed a water-distribute'r F is provided and located at the lowest central point of bottom B directly beneath the base of the coolingnhamber, when the some isin use. This dietributer may be of any desired con figuration and provided wiih any form of dietributing-aperturesfor instance, those shown at Fand is connected with the exterior of the can by means of n jointed connecting-pipe F lending through a. collar A, provided upon the breast A", and has at its upper end a. funnel F to guide the introduction of water thereto. It will readily be seen that this distributer can be removed fromthe can by separating the joint at F, and the distributing-apertures are so diuposed inthe sides and bottom as to drain from the distributor any milk or cream which may pass into the same if it be left within the can and also to facilitate a. cleansing thereof by projecting water upon the bottom and into the discharge-channel at its highest point, so an to thoroughly cleanse the same. If it be desired not to use the watcr'dinn-illnter, the collar A may be suitably closed by men-us of a plug F, on shown in Fig. R

In accmnpliehlug. tho dill'cront uu-thodn of cream separation and objects of thin invention the parts may he used in rlill'orout uscos-m5 scm blugcs lo cllcut I he \illlllllrv results. lmu using Lhocnn lu pramii-o tliefiwcdish sysu-m of cream separation, the cold water or ll'l,&

will be placed or packed within lho ci'mling chamber E, and nstbc walls thereof are com plctcly surrounded by the milk to he cuolcl the reduced temperature thereof will be transmitted in the fullest degree to the milk. As the cream rises within the space of two or three hours, the same will be indicated upon the upper gage, and at that time the milk can be withdrawn from the cream and the cream afterward removed in a separate vessel. It may be stated that the cover to the coolingchmnher is in place when the strained milk is poured into the can, and the flange E di recls this milk-against. the cold surface of the cooling-can. This can is also used in position when it. is desired to refrigerate t-lle milk either in storage or for transportation, and in such uses the can is adapted for use as a receptacle from which milk or cream may be sold. The assemblage of parts for the purposes just stated is shown in Fig. 3; but it is obvious that. the water-distributor may be left in posit-ion, if desired, as shown in Fig. 2.

lo practicing the diluting system the cooler will be removed and the watendistribnter F placed in position, as shown in Fig. 9. Milk is then introduced not to exceed one-half the capacity of the can, and the remainder of the can is filled with water introduced through the funnel F communicating with the distributor. The milk should be near its normal temperature and the colder the water the better the results obtained.

For the practice of the combined system of cream separation the water distributor and cooler arc to bein their respective positions, as shown in Fig. 2. The cooler is to be filled with water, the colder the better. Put on the cooler-mover and pour in the strained milk, not to exceed eighty-five percent. of the capacity of the milk vessel A. Then introduce through funnel water equal to from ten to twenty per cent. of the quantitypf the milk. The nearer the temperature of the milk lothat an which drawn from the cow and the colder the .water the smaller will be the per cent. of the latter required. The separated milk and cream may be withdrawn as hereinhcfore described.

The can and cooler may be also used for the purpose of reducing, the temperature of milk by passing the name through the can one or more times, as may be required to oblain the dcsired temperature. It will be also obvious that the can may be assembled in various ways to accomplish other methods of cream Fl'jrillilllflll or the cooling, storage, or transportation of milk orcrcu-m. it has also been found particularly desirable to introd uce the water used in diluting systems atthe lowest central point of the bottom of the milk-can, while the particular construction il s ilinu-nl-dnm arr vil'nuluul in any uso of [h n b which the milk is drawn l'lmn Ilu: lancer. n1 ils has,
